My apologies to GaryB, because that link already mentions Splog's list of Czech connectors and gives a number of equivalencies for several languages.
And thanks to rdearman for bringing this to the fore again.
MrHenry is no doubt correct to say that he and I were referring to the same link of connectors. I have discovered my copy in an old backup. Rather than post it here, let anyone who wants it PM me with a valid but "safe" email address and I will send you my copy of the spreadsheet (or can we attach things to PMs?). Here are the particulars about the file I have:
1. This file dates from on or before 13 June 2013.
2. English occupies the first column and contains 448 rows of connectors.
3. The other languages are French, German, Italian, Japanese, Mandarin, Polish (but this column is empty), Portuguese, Russian, Scottish Gaelic, Spanish, Swedish (but this column is empty, too), Turkish and Yiddish.
4. Of the other languages, only Spanish has an equivalent for all 448 English connectors, though some come very close.
5. At the time this copy was made, not every non-English translation was entered by a native speaker. But I think most of them were.
6. There is no guarantee that any translated connector is idiomatic or even correct.
7. If memory serves, every non-English language is tied to the English column, but I suppose someone not familiar with English could make do if their language was included in the spreadsheet.
